Zacatecas Silver Expands Oso Negro Vein System to 3 Kilometres, High-Grade Assays Confirm Drill-Ready Targets — Zacatecas Silver Corp.

Event summary

Phase Two rock chip sampling at Oso Negro returned up to 20.3 g/t gold and 3,480 g/t silver, extending mapped vein system to over 3 kilometres.
Prospecto vein confirmed gold-silver mineralization along its entire 600-metre strike length, with veins up to 3 metres wide.
Both Prospecto and Tere veins are now drill-ready, with permitting and drill plan designs underway.
Total of 510 rock chip samples assayed across two phases, with Phase Two returning higher number and tenor of anomalous samples.
Geological signatures suggest potential for high-grade mineralization at depth in a low sulphidation epithermal system.

The big picture

Zacatecas Silver's expansion of the Oso Negro vein system comes at a time when junior miners are under pressure to demonstrate high-grade discoveries to attract investment. The project's location in Sonora, Mexico - a prolific mining district - positions it favorably compared to peers. The company's recent financing provides the capital needed to advance multiple projects simultaneously, potentially creating a portfolio play for investors.

What we're watching

Drill Program Timing: The pace at which Zacatecas Silver initiates and completes its planned diamond drill program at Oso Negro will determine the speed of resource definition.
Mineralization Continuity: Whether the high-grade surface mineralization extends at depth will be critical for establishing economic viability of the deposit.
Permitting Progress: The efficiency of obtaining necessary permits for drilling and potential future development could impact project timelines.
